LOOSE-LEAF BOOK."

Application filed June 2 1, 1920.. Serial No; 390,672.

To all iii/20m it may concern Be it known that I, RALPH G. vVI-IrrLooK, a citizen of'the United States, resid ng at the city of Los Angeles, county of Los 5 Angeles, State of California, have invented new and useful Improvements in Loose- Leaf Books, of which the following is a specification.

My invention relates to improved means for guiding the leaves of aloose leaf book when opening and closing the book. A further object is to provide means for holding plan of the blank for one of the ringframe plates. F 6 is a plan of the blank of the pencil-holding arch band with vprongsbent therefrom.

"Referring to the drawings, 5 is one of the sides of the cover. Each of the sides are alike and only one will be described. In

the back, 6 of the cover is a back plate 7 which has lugs 8 struck up therefrom which are pierced for the passage therethrough of rod 9, which rod also passes through lugs 10 of the ring frame plates 11, whereby the ring frame and cover are secured together. The ring frame consists of plates 11 and the side members 12 and 13 whose ends are turned toward each other, and are connected by rivets 14, and half ring members car- =ried by the side members. The end of the blanks for plates 11 are slotted and are bent downwardly and then inwardly and form 7 pockets 15 in which the side members are mounted, and in which they slide as the book is opened or closed. To the side members are secured the curved half-ring leafholding members 16 and 17, which are arranged in pairs and on which the leaves 18 are mounted.

At each pair of leaf rings and secured to plates 11 by having their reduced ends passed through slots 11v and turned, are arch bands 19 against which the inner edges of the leaves abut when the book is opened or closed. To better effect the closing of the book I provide a closure plate 20 for receive the rollers 22 in such slits.

: each of the sides of the cover. The inner edges of plates 20 are slitted at 21 andthese slits straddle the leaf rings. Secured to plates 20 and mounted in these slits are rollers 22 which bear against and rollupon the leaf rings as the book is opened or closed. A strip of metal 27 has elongated apertures 28 cut therein and is doubled and the slits straddle the half-ring members and A rod 29 is passed through the folded metal and through the rollers. The metal strip is then secured by rivets 30 to the inner edge of plate 20 as shown in Fig. 1. .An end of such strip before folding is shown in Fig. 4. The sides of the cover are each provided with an elongated chamber 23 in which is mounted a coiled spring 24. These. chambers have a slit that opens toward plates 20 through which projects an L-shaped pin 25. One end of pin 25 is secured to plate 20 and the other end projects into spring 24, as

shown in Fig. 2. Spring 24 keeps rollers 22 in engagement with the leaf rings as the book is opened or closed, thereby preventing the leaves from catching on the rings .as they turn. Other means may be used for tensioning the closure plates. It is desirable to have a pencil handy for making entries in the book, and to provide means for holding the'pencil when not in use, I

strike prongs 26 from one of the arch bands at one of the ends of the book, and turn these prongs inwardly-so that when a pencil is pushed into the prongs they will grip and hold it. A blank with prongs is shown in Fig. 6. I may make these prongs separate from the arch band, connect them together, and slide them into the band.

Having described my invention, I claim: 1. A loose leaf book comprising a ring frame composed of side members hinged together, and half ring members secured to said side members, and ring frame plates having pierced lugs, said plates being mounted on said side members; leaves mounted on said ringsga cover having a back plate rovided with pierced lugs, and a rod passing through the lugs of the ring frame plates and the lugs of the back plate ofthe cover, whereby the ring frame is secured to the cover; covers each having a chamber opening toward the inner side; a. spring in each of said chambers; closing plates having slitted inner edges which straddle the whereby When the book is opened or closed the leaves are prevented from sticking on the rings.

3. In a loose leaf book having a ring frame, said frame having ring frame plates, an arch band having prongs struck therefrom and turnedinwardly, said arch band being secured to a ring frame plate thereby forming means to retain a pencil.

In Witness that I claim the foregoing I have hereunto subscribed my name this 14th day of June, 1920.
